Example
- Age
- 40 years
- Burned total body surface area
- 30 %TBSA
- Inhalation injury present
- Yes
Result: Revised Baux score 87 — lower predicted mortality.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 130
- Lower predicted mortality: age + %TBSA + 17 if inhalation injury.
- 130-159
- Around the LD50 for well-performing modern burn units (~130-140).
- >= 160
- Near-universally fatal even with modern care. A prognostic estimate, not a triage order.
What you enter
- Age
- Burned total body surface area
